For the pressure test is the test supposed to be performed by bending their knee or keeping their legs straight? Which test gives you better results? Measuring the compartments by using a needle or the probe? Thanks in advance

Compartment pressure. Compartment pressure measurements are performed at baseline with follow up measurements after 5 minutes of running. Needle placement is performed in all four compartments --anterior, lateral, posterior and deep posterior regions of the leg. A baseline blood pressure allows one to assure that the pressure measurements can be properly interpreted.
